8 Claims.

The present invention relates to fly-tying bobbins. I

In the making of flies for fishing purposes, the flies are usuallyformed on the fish hook. To accomplish this, feathers of differentcolors are tied to the hook by means of thread. Usually the thread iswrapped around portions of the feathers and the hook, the final flybeing of a form which is attractive to a fish, causing it to snap at thefly and thus engage the hook. The making of flies has become an art,requiring a means for rapidly forming the fly on the hook.

An object of the present invention is to provide a means whereby threadmay be rapidly wrapped around the various feathers and the hook to forma fly, the operator at all times being able to observe his handicraft.

A further object of the invention is the provision of a device for tyingflies which is easily manipulated, and which assures a better flyconstruction.

It has been found that use of the present invention increases anoperators speed in the forming of flies on a fish hook. It is notuncommon for an operator with fair skill using the present device toform thirty flies an hour.

A further object of the invention is a fly-tying bobbin which is simpleof construction, easily loaded with thread, attractive in appearance,inexpensive in cost of manufacture, and superior to devices now known tothe inventor.

In the drawing:

Figure 1 is a side view of the invention looking in the direction of thearrow I of Figure 2,

Figure 2 is an end view looking in the direction of the arrow 2 ofFigure l, and,

Figure 3 is a sectional view on an enlarged scale, taken on the line 3-3of Figure 1.

Referring now to the drawing:

The fly-tying bobbin of the invention is designated as an entirety bythe numeral I, and includes a body 2, one portion 3 of which is ofuniform external diameter, while an elongated concavedly tapered portion4 extends from said portion 3 to form an extension or nose portion. Theportion 3 is provided with an enlarged bore 5 opening outwardly from oneend of the body, as shown at 6; while the wall adjoining said bore 5 andinwardly of the body is concavedly reduced in diameter, as shown at I,to where it merges and communicates with an axial bore 8 in theextension or nose 4, and which bore 8 in turn communicates with areduced diameter axial bore 9 extending to the tip ID of the nose. Theportion 3 is formed with axially aligned transverse bores II and I2,bore I2 being of greater diameter than bore II; portion 3 is boredinwardly at I3, and communicates with bore II. The bore I3 is reduced indiameter at I4. Such reduction may be accomplished in any convenientmanner, such as by peening the end of the body adjacent said bore whereit communicates with the bore II. Bore I3 is adapted to receive a ballI5, which projects within bore I I, said ball being urged to saidposition by a coiled spring I6 held within the bore I3 by a nut I! inengagement with threads formed in the wall bounding the bore I3. Abobbin I8 extends between and is received in part within the bores IIand I2. The bobbin is of the usual spool type, having heads I9 and 20.The head I9 has a diameter slightly less than the internal diameter ofbore II, and said head is formed with an annular groove 2 I. The head 20has two portions of different diameter, as shown at 22 and 23, theportion 22 fitting snugly within the bore I I, while the portion 23engages the outer surface of the portion 3 and limits movement of thebobbin in one direction. The portion 3 is formed with a transverse slot24 extending from the end of said body to the bore I2.

The operation, uses and advantages of the invention just described areas follows:

The bobbin is wrapped with thread 25, whereupon the thread, with thebobbin exterior of the body, is passed through the bores 8 and 9. Thismay be accomplished by running a needle having a hook end through thesaid bores to contact the thread and draw the same through the saidbores. After this is accomplished, the bobbin may be placed in the bodyby passing the head I9 first through bore I2 and then into bore II, atwhich time the spring-pressed ball I'5 will be received within theannular groove 2|. The thread may then be passed through slot 24 so thatupon pulling that portion thereof which extends through the tip I0, thethread will assume the position shown in Figure 3. The ball I5 exertsenough pressure against the head to permit easy rolling of the bobbin,and just sufiicient friction to maintain a proper tension on the thread25 when the thread is being used to form a fly. In other words, thespring-pressed ball acts as a friction means for the bobbin.

The operator, in the use of the invention, uses a suitable clampingmeans for holding the fish hook. He then takes the various objects whichmake up a fly, such as small feathers, and while holding them in onehand against the fish hook, rapidly wraps the thread about the hook andthe feathers, adding such other objects as may be necessary to form acomplete fly. The long pointed nose of the device allows the operator torapidly wrap the thread about the fly and the hook, and further permitsa tying thereof when desired. Proper tension is maintained on the threadby maintaining a friction means for the bobbin. The use of this deviceassures that the fingers O-fathfl operator-are not brought into con-1tact with the impalingaportioniofiftheahook; the result that theoperator does not suffer any injury to his fingers while forming thefly. The 1 long tapered nose permits the operator to watch the formingof the fly at all times, his vision not being obscured as would be thecaseif-he utilized;

the fingers of both hands for Wrapping and tying the thread about thehook and the fly.

I claim:

1. A device of the character disclosed, including a cylindrical bodyformed with .an elongated conical extension, both the extension and'saidbody; formed with coaxialbores, said'bodyiprovided with diametrically.positionedv transverse bores, a bobbiniormed with head portions, thehead portions adapted to be received within the transverse bores,andifriction means for engage? ment'with aheadportion of the bobbintoii'mpose a tension uponlanyuthread'carried by the bobbin and passedthrough and outwardlyof the bores in said Ltapered extension.

2; A device of the character disclosed; includ ing an annular bodyportion formed with an elongatedftaperedextension, the extension beingpro.- videdwithan axial bore communicating with the vinterior of the.annular body; said annular body axially bored, the diameter of the boresin the extension being small in comparison to the diameter of the borein the body; said body being transversely bored; a bobbin having headportions for reception within said transverse bores, saidwodyformed witha transverse slot extending fromthe end of said body to one of saidtransverse bores, said transverse slot permitting any thread on thebobbin to be passed within the'body.
